Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0201 AM CDT Sun Aug 03 2025

Valid 031200Z - 041200Z

...Synopsis...
A midlevel trough will move eastward from the eastern Pacific into
the Northwest through the period. Within the base of the trough,
enhanced midlevel westerly flow will overspread a dry/deeply mixed
boundary layer across the Great Basin during the afternoon. This
will favor breezy/gusty surface winds (around 15-20 mph) amid
single-digit to lower teens RH, and given receptive fuels, elevated
fire-weather conditions are expected.

Preceding the trough, forcing for ascent will aid in afternoon
thunderstorm development across the northern Great Basin and
Intermountain West. Across parts of northern CA, southeastern OR,
and southwestern ID, inverted-V soundings (around 0.5-0.7 inch PW)
and quick storm motions will lead to mostly dry thunderstorms. These
storms will pose a risk of lightning-induced ignitions and
strong-severe outflow winds. For details on the severe-storm risk,
see the SPC Day 1 Convective Outlook. A mix of wet/dry thunderstorms
(with higher storms coverage) are also expected farther north across
east-central OR, though these storms should be accompanied by
measurable rainfall. Lightning-induced ignitions will still be
possible along the peripheries of rain cores.
